EMPTYING EQUIPMENT FOR PLASTIC BAGS.

DESCRIPTION

The invention concerns an emptying apparatus for bags made of plastic material.

Nowadays in the hospital sector, catheters are recognized as 'waste at risk of infection' and must be treated as such according to national and international standards and regulations.

For example, waste at risk of infection must be collected in yellow bags which are then placed in special yellow rigid plastic containers, and the rigid containers must be carefully hermetically sealed.

? It is necessary to wear specific personal protective equipment during closing and transport maneuvers, in order to avoid risks of contact with or inhalation of dangerous substances.

Finally, such waste at risk of infection must be sterilized.

The sterilization of hazardous medical waste at risk of infection must be carried out in facilities authorized in accordance with the law, with which a healthcare facility must therefore be equipped; alternatively, hazardous medical waste at risk of infection must be transported to external sterilization facilities, with consequent transport costs. These currently known disposal systems for catheters therefore require that the plastic bags are destroyed together with the contents, with consequent waste of raw material.

Alternatively, the catheters, if they come from patients undergoing particular therapies for which the collected body fluids may be dangerous, are emptied in particular equipped areas, with suction hoods and complex and expensive exhaust systems; these systems however expose an operator to risks of contagion or contamination.

Task of the present invention? that of developing an emptying apparatus for bags made of plastic material capable of overcoming the aforementioned drawbacks and limitations of the prior art. In particular, one purpose of the invention is? that of developing equipment capable of emptying catheter-type bags safely and effectively, without risks of contamination or contagion for operators.

Another purpose of the invention? that of developing equipment that operates automatically.

A further purpose of the invention? is to develop a compact and easily set-up device even in healthcare environments already existing.

An important purpose of the invention? is to develop, as requested by the authorities? healthcare, an equipment capable of emptying and sanitizing bags containing urine and/or other liquids considered dangerous, for a healthcare worker, due to the fact that they contain dangerous contaminating substances if dispersed into the environment during emptying.

It is therefore an aim of the present invention to develop an apparatus capable of defining a closed circuit system with a water network to which? connected.

The task as well? the above-mentioned purposes are achieved by an emptying apparatus for plastic bags according to claim 1.

Further characteristics of the apparatus according to claim 1 are described in the dependent claims.

These connectors 55, 55a, 55b, 55x are intended to be similar to the connectors 13, 13a, 13b, 13x of the first manifold assembly 14.

The number 55x refers to a generic connector of the second manifold assembly 52.

Each of the connectors 55, 55a, 55b, 55x also includes a one-way valve configured in such a way as to:

- allow the passage of washing water in both directions when a connection 60 of a drain pipe S2 of a bag S? inserted into a corresponding socket 56 of the connector 55, 55a, 55b, 55x,

- prevent the exit of liquid from the connector 55, 55a, 55b, 55x and therefore from the second manifold assembly 52 when the connector is not coupled with a 60 coupling.

The 60 coupling, for example, is the extremity? of the tap S3 of the bag S, as exemplified in figure 15.

Each coupling 60 ? locked in the coupling position by means of reversible locking means 62, clearly visible in figure 15. For each of the connectors 55, 55a, 55b, 55x, the locking means 62 include a rotatable bracket 63 pivoted to the body of the connector 55, 55a, 55b, 55x via a pin 64.

This rotating bracket 63 includes a locking appendage 63a shaped to be positioned above the tap S3 so as to prevent its decoupling from the socket 56 of the connector 55, 55a, 55b, 55x.

Compared to what is described above, instead of one-way valves, manual valves or electro-controlled valves may be present, in order to open and close the connectors connecting to the S bags depending on the need.

The sealing gaskets between the connectors 13, 13a, 13b, 13x, 55, 55a, 55b, 55x and the respective inlet tubes S1 or exhaust tubes S2 of the bags S can be replaced by silicone tubes or thermoplastic rubbers with dimensions suitable for the variants of the bags on the market adopted by the healthcare facility where the equipment is 10? installed.

In the present embodiment, which does not limit the invention, the support structure 11 includes:

- a 70 bag trolley,

- a cabinet 71, configured to contain the discharge line 15, the first loading line 17, the second loading line 19 and the tank 18.

Wardrobe 71? supported by a sliding frame 72, equipped with ground support wheels.

Alternatively, wardrobe 71? fixed to a wall.

The bag trolley 70 includes:

- a box-like containment body 73, equipped with doors 74 for access to its interior,

- a load-bearing element 75, fixed inside the box-shaped body 73, to which hanging means 76 are fixed for a plurality of of bags to empty S,

- a support cover 77 for the first manifold assembly 14.

The first collector group 14 ? fixed above the cover 77 so as to be available for connection with the drain line 15 contained in the cabinet 71.

In the present embodiment, the load-bearing element 75? consisting of a plate placed vertically, with respect to the normal position of use, and fixed to two opposite walls of the box-like containment body 73. In particular, the load-bearing element 75 is consisting of a vertical plate positioned in a central area of the box-like containment body 73.

The cart ? it is understood that it can also be without doors, as exemplified in figure 16; the cart there? indicated with the number 270. In the case of a trolley 270 without doors, the wardrobe 271 has a lower part 271a configured to accommodate the trolley 270 inside it; this lower part 271a? equipped with doors that can be opened 274 to allow the passage of the trolley 270 and which can be closed to protect the trolley 270 itself during the emptying and sanitizing phases of the bags S contained therein.

The 270 trolley? to be understood as being able to be equipped with a first collector group and a possible second collector group different and equivalent to those described above, depending on the different types and configurations of the S bags that are in use at the healthcare facility in which the equipment 10? installed.

At the bottom of the cart 70 and 270 ? there is a removable safety tank, configured to collect the liquid that leaks from a malfunctioning connection or from a torn S bag; this removable safety tank, not illustrated for simplicity, is such as to contain at least the contents of a full bag S; this removable safety tank has inside it a sanitizing substance, for example of the gel type, configured to neutralize any exhalations of urine and/or other liquids leaking from the S bags above; such a removable safety tub? made of material suitable for sanitisation.

The hanging means 76 comprise, for example, a plurality of of hooking and locking devices 77.

Each coupling and locking device 77 ? of the pliers or vice type.

For example, a coupling and locking device 77 includes: - a spacer body 79 fixed to the supporting element 75,

- a threaded bar 80 partially screwed to the spacer body 79 in a substantially horizontal position,

- a clamping jaw 81, crossed by the threaded bar 80 and configured to be movable along the same threaded bar 80, - a locking and unlocking knob 82, fixed to the end free of the threaded rod 80.

The threaded rod 80? consisting, for example, of a screw.

The clamping jaw 81 ? made up of a plate.

Between the spacer body 79 and the clamping jaw 81 ? interposes an elastic thrust element; such an elastic thrust element? for example a coil spring 83 coaxial to the threaded rod 80.

Position the upper edge of a bag to be emptied S between the spacer body 79 and the clamping jaw 81 and proceed with the rotation of the locking and unlocking knob 82, so that the clamping jaw 81 presses the upper edge of the bag S against the spacer body 79; the coil spring 83 is compressed.

The reversible locking of the bags to be emptied S? therefore simple and quick to carry out even for an operator who has not been provided with particular pre-teaching.

To free a bag to be emptied S at the end of the emptying operations, operate in the opposite way, with the helical spring 83 pushing the clamping jaw 81 away from the spacer body 79.

In the present embodiment, the trolley 70 includes eight coupling and locking devices 77; this number? to be considered indicative and not restrictive of the invention.

The trolley 70, and 270, which is? therefore collection and transport for the S bags, ? designed to be able to be moved up close? of patient beds, reducing the risks of contamination that can running an operator in the process of replacing, on a patient's premises, a full bag with an empty bag; this risk reduction is achieved by transferring a full bag directly onto the trolley 70 or 270, immediately connecting the connection ways of the bag S to the connectors 13, 13a, 13b, 13x, and possibly 55, 55a, 55b, 55x if present, of which the 70 or 270 trolley? gifted.

Wardrobe 71? supported at a height such as to allow the trolley 70 and 270 to be placed underneath the same cabinet 71.

In particular, wardrobe 71? positioned in such a way that the lowering of the mobile tube 38 allows the latter to couple with the sleeve 36 of the first manifold assembly 14.

The cabinet 71 includes a box-like body equipped with a door 87 for access to the tank 18 and a load-bearing surface 89, the latter indicated in figure 9.

Below the tank 18, or between the tank 18 and the load-bearing surface 89 which supports it, there is a filling sensor is placed which monitors the progressive emptying of the same tank 18; such a filling sensor? connected to a signaling system when a minimum filling level is reached; this signal allows an operator to restore the correct filling of the tank 18 and therefore the correct functionality? of the equipment 10. The cabinet 71 includes a control panel 88 for managing the equipment 10.

The cabinet 71 has a guide slot 90 configured to be crossed by the operating lever 39 and to allow the movement of the operating lever 39 between two positions:

- a first raised position, i.e. with the operating lever 39 at the upper limit switch, in which the mobile tube 38 is translated upwards and disconnected from the sleeve 36 placed on the first manifold assembly 14, - a second lowered position, i.e. with the operating lever 39 at the lower limit switch, as shown in figures 4 and 5, in which the mobile tube 38 is translated downwards and ? coupled with the sleeve 36 located on the first manifold assembly 14.

The operation of the apparatus 10 according to the invention is described below.

Therefore, the object of the present invention is also a method of emptying a plurality? of bags to be emptied S containing dangerous waste, such as liquid waste at risk of infection from hospital facilities.

Preparatory operations for the actual emptying phases are the following:

- hook up a plurality? of bags to be emptied S each to a corresponding coupling and locking device 77 of the trolley 70;

- connect each inlet tube 29 of each bag S to a corresponding connector 13, 13a, 13b, 13x of the first manifold assembly 14,

- place the trolley 70 underneath the cabinet 71,

- lower the operating lever 39 so as to connect the exhaust line 15 with the first manifold assembly 14.

The draining method includes the following steps:

a) open the first loading line 17 so that the water flows from the sampling point P1 into the bags to be emptied S so as to fill them without causing them to break,

b) close the first loading line 17 and open the discharge line 15, c) start the suction pump 16 so as to empty the bags S and send their contents, diluted with the loaded water, to the discharge point P2,

d) stop the drain pump 16, close the drain line 15, e) open the second load line 19,

f) start the pump 50 of the second loading line 19 to introduce a quantity into the discharge line 15? of sanitizing substance, g) stop the pump 50 and close the second loading line 19, h) open the first loading line 17 again so that the water flows from the sampling point P1 into the bags to be emptied S , so as to fill them without causing them to break; in this way the sanitizing substance mixes with the water coming from the sampling point P1 and reaches the bags S;

i) close the first loading line 17 and open the discharge line 15, l) start the suction pump 16 to empty the bags S and send their contents to the discharge point P2,

m) stop the drain pump 16, close the drain line 15. Phases from e) to m) define a sanitization cycle.

This sanitization cycle, i.e. the sequence of phases from e) to m), can? be iterated once, or twice, or more? times depending on the needs? and the sanitization needs of the S bags.

Thanks to this method it is possible to empty and sanitize a plurality at the same time. of bags to empty S, for example eight bags to empty S.

The number of iterations of the sanitization cycles can? so depend on the quality? of the washing and sanitization that you want to obtain for the S bags.

The control program of the equipment according to the invention, which is therefore application of the operating method, allows you to select, with a button, a washing program suited to the number of bags to be emptied, washed and sanitized, where these bags can be in a quantity? from 1 to 'n' bags, depending on the machine model and the type of bags.

This indication of the number of bags to be emptied, washed and sanitized? necessary in the event that, at the end of the day or at the end of the shift, an operator who uses the equipment according to the invention deems it necessary to empty the collected bags without having to reach the maximum number of bags that the trolley can accommodate? to contain.

In fact, in the washing phase, and not in the emptying phase, if for example there was only one bag to empty and wash, the quantity? of water with sanitizer entering the individual bag would be excessive and would cause the bag itself to explode during filling; then ? It is therefore necessary to select a corresponding number of bags in the washing program, i.e. for example only one bag, so that? the equipment? called to employ a quantity? of water such that the single washed bag does not explode.

The apparatus 10 in its first embodiment, visible in particular in figures 1, 3 and 4, is configured for use with emptying bags S of the type having only an inlet tube S1 and not also an outlet tube S2.

Such bags to be emptied S are for example urine collection bags for urinary catheters.

These S bags are intended to be of the type normally used in healthcare facilities; these bags S can have only one entry and exit route, in this case the emptying and washing are carried out through the same entry and exit tube S1; the S pockets can also have an access route and a different exit route, as more? described below.

In this equipment 10 the fluids pass through the connectors 13, 13a, 13b, 13x of the first manifold assembly 14 in both directions, i.e. both from the bag S towards the discharge point P2, and from the withdrawal point P1 towards the bag S.

The apparatus 110 in its second embodiment, visible in particular in figures 2, 5, 9 and 12, is configured for use with emptying bags S of the type having an inlet tube S1 and an exhaust tube S2, normally equipped with a corresponding tap S3.

Such bags to be emptied S are for example urine collection bags for urinary catheters equipped with a drainage tube and emptying tap. In this equipment 110 the fluids pass through the connectors 13, 13a, 13b, 13x of the first collector group 14 and also through the connectors 55, 55a, 55b, 55x of the second collector group 52 in both directions, i.e. both from the bag S towards the discharge point P2, both from the withdrawal point P1 towards the bag S.

Preferably, in order to optimize and balance the filling of the bags S, the liquid passage channels of the connectors 13, 13a, 13b, 13x of the first manifold assembly 14 and the liquid passage channels of the connectors 55, 55a, 55b, 55x of the second collector group 52 have the same cross section.

The equipment 10 and 110 also includes a protective door 91 configured to cover the first manifold assembly 14 when this is coupled to the discharge line 15, with the trolley 70 positioned underneath the cabinet 71.
